Description:
Abstract:
These data include water chemistry from springs, streams, rivers, and shallow groundwater collected in the Arctic National Wildlife Refuge in northern Alaska. Chemical analyses were performed for hydrochemical parameters including field parameters, major ions, nutrients, metals, stable isotopes of water, and tritium, as well as for dissolved gases useful for determining the timescale over which the water was in the subsurface (i.e. age dating tracers), including noble gases and chlorofluorocarbons.
Purpose:
These data were collected to help determine the sources and ages of waters contributing to the flow of rivers in the Arctic National Wildlife Refuge as part of a completed U.S. Geological Survey Project.

Process_Step:
Process_Description:
Stream water quality parameters (temperature, specific conductivity, pH, and dissolved oxygen) were measured in situ using a YSI EXo1 or YSI Professional Plus multi-parameter instrument. All probes were regularly calibrated following standard methods.
Process_Date: Unknown
Process_Step:
Process_Description:
Samples were collected in the field using a peristaltic pump. Silicon tubing (size 15) was connected to a Geotech 2 peristaltic pump to collect water samples, approximately 25-50 cm below the stream surface in a well-mixed location. Samples were filtered through a 0.45 micrometer capsule filter. Samples were stored in a cool dark place until they were delivered to a laboratory for anlysis.
Process_Date: Unknown
Process_Step:
Process_Description:
Major anions (chloride, nitrate, and sulfate) and cations (sodium, ammonium, potassium, magnesium, and calcium) were analyzed by D. Repert at the U.S. Geological Survey (USGS) laboratory in Boulder, CO. Samples were analyzed on a Dionex ICS 5000 Ion Chromatograph (Dionex Corporation, Sunnyvale, CA, USA). Anions were analyzed using an as4a-sc analytical column, ag4a-sc guard column, and a bicarb-carbonate elluent. Cations were analyzed using an cs12a analytical column, cg12a guard column, nad a methane sulfonic acid elluent.
